Winning the British Open wasn’t enough to make Rory McIlroy want to take the rest of the year off to celebrate. Neither was the first World Golf Championship he won yesterday at Firestone in Akron.

Another major awaits next week. McIlroy can’t wait to get there.

Two weeks after his wire-to-wire victory at Royal Liverpool, McIlroy took his game from the links of Britain to the parkland of America and made the game look just as easy. With another powerful performance, he wiped out a three-shot deficit to Sergio Garcia in three holes, closed with a 4-under-par 66 and returned to No. 1 in the world with a two-shot victory at the Bridgestone Invitational.

He looked just as good as the last time he reached No. 1 in the world during his torrid stretch at the end of 2012.

“This is better,” he said. “Mentally, I’m really sharp. I didn’t start to think about score. I didn’t think about where I was in the tournament. I was just playing shot after shot after shot. So yeah, it’s good.”

Garcia wasn’t at his best and closed with a 71. He’s not sure it would have mattered.

“Everybody saw it,” Garcia said. “He played very, very well. He drove the ball miles and very, very straight for the most part.

“He gave himself a lot of birdie looks.”

McIlroy became the 13th player with a major and a World Golf Championship, and he joined Tiger Woods as the only players to win them in consecutive starts. Woods wasn’t around to see it.

Four months after back surgery, and in his third tournament since his return, Woods injured his lower back when he landed with a thud in the sand from an awkward stance atop a bunker on the second hole. He withdrew after a tee shot on the ninth hole, bending over slowly and struggling to remove the tee from the ground.

It was not clear whether Woods will play in the PGA Championship next week.

McIlroy heads to Valhalla in Louisville, Ky., with a full head of steam. After a brief celebration with the claret jug, he was determined to move forward and chase more titles over the final four months of the year.

McIlroy backed it up with a powerful performance on a soggy Firestone course to take the top spot in the world from Adam Scott.

“That’s the most pleasing thing about this week is not dwelling about what happened at Hoylake,” he said. “That’s what I’ll have to do after this, as well. I’ve just got to keep moving forward. It’s great to have a chance to try to go there to win three in a row. But if you’d have asked me what I’m proudest of this week, it’s the mindset that I took into here of not being complacent. I wanted to come here and really contend.”

McIlroy finished at 15-under 265 and won $1.53 million, leaving him $765 short of Bubba Watson on the PGA Tour money list.

Garcia was a runner-up to McIlroy for the second straight time. Marc Leishman (67) finished alone in third at 12 under.

PGA Tour

Geoff Ogilvy won the Barracuda Championship in Reno, Nev., for his eighth PGA Tour title and first since 2010, earning five points with an eagle on the par-5 13th and pulling away for a five-point victory in the modified Stableford event.

Champions Tour

Kenny Perry scrambled for a birdie on the 18th hole to defeat hard-charging Bernhard Langer by a stroke at the 3M Championship in Blaine, Minn.

Perry closed with a 7-under 65 for his second victory of the year and seventh overall on the Champions Tour. He finished at 23-under 193.
